IMPROVEMENT IN BARREL-MACHINES.

Specification forming part of Letters Patent No. 58,729, dated October9, ISGG To all whom. t may concern:

Be it known that I, P. H. LA\VLER,ot'Roel1 ester, in the county ofMonroe and Sta-te of New York, have invented certain new and usefulImprovements in Barrel-Head Gutters; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, refereneebeing had to the accompanying drawings, making part of thisspecification, in which- Figure lis a top view oflny invention. Fig. 2is a vertical section of the same, taken in the plane of the red line 0in Fig. l.

Similar letters indicate like parts in both figures.

This invention relates to that class of barrelhead-cutting machines inwhich the dishing saw is used; and its nature consists, mainly, insuspending the clamping-collars upon a swinging standard, the axis ofwhich is parallel, or nearly so, with that of the saw, while that of theclamps is arranged about in the same angle with relation to thesaw-mandrel -as heretofore, and also in so arranging the axis of theframe of the clamps that the gravity of the parts shall cause it toswing to the open position, or away from the saw.

To enable others to make and use my invention, I will describe itsconstruction and operation.

I provide a frame, A, of suitable height for the convenience of theoperator. The saw mandrel or arbor B, I arrange across the corner of theframe, as shown in Fig. 1, in fixed bearings C.

The axis of the clamping-collars D and E is in the top of the standardE, which is hung to the frame A, as shown in Fig; 2, in such a manner asto cause the clamps to swing from the saw by its own gravity whenreleased by the spring-catch G and the lug or clamp H.

The shaft I is made to slide longitudinally in its bearings J and J',and the outer end is provided with a pivoted coupling, by which latterit is connected to the cam-lever L; and there being a strong spiralspring, s, placed between the journal-box J and the spur-wheel W, whenthe clamp is set, as indicated by the full lines in Fig. 1, this springs is compressed 5 and, as may be seen, when the frame E is released bythe spring-latch', the spring s forces the mandrel back, and by pressingthe canrlever L against the face ofthe inclined plane M, thecounterbalaneing is greatly assisted, and the clutch a on the end of thelever catches at the point indicated at a', and secures the frame inthat position until it is again thrown forward by the operator, which isusually done by pressing' down the lever N, Fig. 2, with his foot. Thecord or chain It runs over the pulley T and connects the lever and frameF.

The headingstuff is placed between the eollars D and E, they being'spread and in the position indicated by the dotted lines Dl and E', thelower edge resting upon the gages or dogs g and 7i, which only reach toia short distance beyond the face of the collar D. The operator theneffects the clamping by press-A ing the lever N, as before stated, andas the clamping-.frame reaches the position shown by full lines inthedrawings the spur-wheel WV is brought into gear with the feed-wheel c.The clamping collars are thereby rotated, while the saw P forms thecircle; which being completed, the pin t' strikes the end of thespring-hook Gr and releases the clutch H, when the frame or standard Ereturns to the open position, releasing theiormed head, and it drops tothe spout Y, Fig. 2, by which it is conveyed from the machine. v

The feed wheel c is driven by a band on the pulley p from acounter-shaft.

The pin u in the spur-wheel lV is placed about opposite to the pin t',that unhooks the clamp H, and as the frame swings back toward theposition of the dotted lines, the pin u strikes the face of the inclinedplane or cani m, and causes the wheel to turn partially around backwarduntil the pin z' strikes the under' side of the latch G, so that whenthe next head is clamped the wheel shall make so much more than arevolution. lThe object of this is to cause the saw to cut at least thefull circle of the head or a little more. The cam m is made adjustable,whereby it may be set as desired.

What I claim as my invention, and desire to secure by Letters Patentis== l. Hanging the clamping-frame F upon an 2 55,729 v l n axisarranged diagonally with relation to that 3. The arrangement, with thesliding manot the clamping-collars, and parallel with redrel I in theswinging frame F, of the spring lation to that of the saw, as and forthepurs, the pivoted lever N, and cam M, substanposes set forth. tiallyas shown, and for the purposes set forth. f
